,This invention relates to an improvement in spinning-machines. 7

One object of this invention is to provide a suitable attachment to be used on spinning machines which will collect the yarn during the dofiing of the spinning pots.

Another object of this invention is to provide a suitable attachment which may readily be moved into operative positions when the spinning pots are being changed.

These and other objects of this invention will become more apparent from a perusal of the following description and a study of the drawing in which:

Figure l is a diagrammatic view of a portion of an artificial silk spinning machine showing the attachment in operative position and Figure 2 is a view showing a modified form of attachment.

In the spinning of artificial and kindred threads and filaments, the threads are spun into a suitable coagulating solution and passed over suitable guiding and stretching means to a rotating spinning pot where they are collected. When the pot is filled it is necessary to remove it and place another one in position. Since, because of the nature of the spinning process it is very inefiicient, if not impossible, to stop the flow of the spinning solution into the coagulating medium, means are usually provided to collect the freshly spun thread during the changing of the spinning pot, or what is generally known as the dofiing period. Heretofore the thread has been cut and the end thereof wound on a spare roller. This method was extremely dissatisfactory since the thread collected on the spare roller was not only worthless but rendered the apparatus unsightly and dirty.

According to this invention. the thread 10 emerging from the coagulating hath (not shown) is passed over a take-up roller l1 and is led downwardly through the a spinning pot spinning funnel l2 into (not shown). Positioned adjacent the takeup roller and extending downwardly along the machine is protective wall or guard 13 made of lead or other suitable mate- 571,474, and in Germany February 13, 1931.

rial. A gutter 14 is located beneath the take-up roller to receive the liquids which are brought to the take-up roller by the freshly spun thread.

The attachment comprises a horizontally positioned platform or table 15, made preferably of sheet aluminium and is provided at one end with a vertically extending member terminating in a hook 16 which fits over one side of the gutter. During the normal operation of the spinning machine, the attachment is placed in inoperative position and the thread is collected in the spinning pot. When the latter becomes filled, the thread is out between the spinning funnel and take-up roller, and the attachment is moved into position so that the thread can accumulate during the exchange of an empty spinning pot for the one filled with thread. After the empty pot is in position the thread is again out and the attachment moved out of the way. The

end of the thread is inserted into the spinning funnel and the normal operation of the machine continues. The thread collected on the attachment ,is thus clean and has an absolutely even denier corresponding to the rest of the artificial silk. This thread may readily be collected, washed and used for schappe.

In Figure 2 there is shown a modified form of attachment in which the member extending vertically from the table or platform l5 is provided with a bracket 17' carrying a pintle on which is pivotally mounted the movable arm 18 of a clamp I9, the vertically extending member forming the fixed arm thereof. The movable arm is pressed against the fixed arm by means of the spring -20. By this construction the attachment may be shifted along the lower end -21 of the protective wall or guard 13. The use of this attachment is similar to that shown in Figure 1.

From the above description it will be seen that there has been provided a simple and eflicient attachment which may readily be moved in operative position; and which will collect the thread during the doifing between said take-up period. This thread, so collected, will not be waste, may be used for schappe. 7

Although the invention has been described with reference to the specific embodiment disclosed, it is to be understood that the invention is not specifically limited thereto, but may be modified in many details without departing from the spirit of'the inven-' tion or the scope of the appended Claims.

What is claimed is:

1. A machine for spinning thread having" a take-up roller, a gutter located therebeneath, a guide means, a platform located between said take-up roller and guide means, movably secured to said gutter and adapted to receive the thread during the dofling operation.

2. A machine for spinning thread having a take-up roller, a gutter located therebeneath, a guide-means, a platform located roller and guide means, and adapted to receive the thread during the doffing operation.

3. A machine for spinning thread including a take-up roller, a guide means located at a distance therefrom and a vertically extending protective member, a platform, .vertically located between said take-up roller and guide-means, and movably secured to said protective member and adapted to receive the thread during the dofiing operation. In testimony whereof I affix my signature.
